Re: Turbo questions 200 1984

posted by  someone claiming to be wbain on  Sat Feb 3 01:09 CST 2001 [RELATED]

Paul gives good advice. I have to report that I still have the original turbo at 260,000 miles and it does whine a little. This is no doubt caused by an imbalance caused by pitting of the blades.

Practically speaking, an extended idle is only necessary after hard driving, such as through the mountains and then having to make a pit stop. The turbo gets really hot and could still be spinning. If you are driving back home and driving through your neighborhood at the required 25 mph, hyour turbo is not working and the engine is not working hard at all. So idel home, sit in the driveway for a short time, less that 30 sec to a min and shit it off. If yours is water cooled, you will have no problems at all due to the water siphoning effect, the hot water in the turbo will rise replaced by cooler water.

The biggest problem would be coking of the oil return line, ie it gets blocked. Another would be the rubber inlet hose deteriorates due to the heat, a problem I currently have. Another problem, broken exhaust manifold studs if you try to remove them.

You also need to fix any oil leaks.

I hope this helps.
